Despite being late for other coming across this:
This is likely due to the service-account.json missing in local_vars or setting$serviceAccountPath to an invalid path.

Also be aware that using newer php versions might not work. For example the signature of implode changed in php 8 (https://www.php.net/manual/en/function.implode.php).
